The authors present two cases of neuroretinitis caused by
infection.

Case 1 is a 24-year-old male who presented with 2 months of vision loss. Case 2 is a 38-year-old female who presented with 4 weeks of eye pain and vision loss. Examination of both patients revealed neuroretinitis characterized by optic disc swelling with macular exudates, and subsequent serological analysis was positive for
. Both patients responded favorably to treatment with oral doxycycline and prednisone.

Given the potential for neuroretinitis to cause permanent vision loss, the presence of acute vision loss, optic disc edema, and macular exudates should prompt an evaluation for Rickettsial disease in endemic areas, even in the absence of systemic symptoms or known history of a tick bite.

To describe a case of Cytomegalovirus (CMV) Retinitis in an immunocompetent patient following Dexamethasone Intravitreal Implant (DII).

Retrospective chart review of a single patient. An 80-year-old immunocompetent male presented with floaters in his left eye 10 weeks after his DII. He was noted to have a visual acuity of 20/1200 in his left eye and a panuveitis with CMV retinitis. The patient underwent a vitreous biopsy and given immediate intravitreal foscarnet and an ongoing management regimen of oral valganciclovir for two months. His vision improved to 20/200 and his CMV retinitis resolved.

DII can trigger CMV retinitis in immunocompetent patients.

To report a case of external ophthalmoplegia due to an uncommon form of amyloidosis exclusively affecting the lateral rectus muscle, and to discuss the clinical manifestation, diagnostic challenges, and management pitfalls of isolated amyloidosis in the extraocular muscle.

A 64-year-old woman presented with diplopia in her left gaze lasting for six months. She had orthophoria in the primary position and abduction limitation in the left eye. Routine laboratory examinations were unremarkable. Orbital magnetic resonance imaging showed fusiform enlargement of the left lateral rectus muscle, without tendon involvement. Extraocular muscle biopsy was recommended to make a diagnosis, which revealed amyloid deposition in the lateral rectus muscle. A systemic work-up showed no evidence of systemic amyloidosis. Therefore, a diagnosis of primary isolated amyloidosis was made. Orthophoria in the primary position and diplopia in the lateral gaze persisted at the six-month follow-up.

Atypical extraocular muscle enlargement should alert clinicians to the need for tissue biopsy to identify uncommon etiologies, such as amyloidosis. There are no pathognomonic or radiological features to distinguish localized from systemic amyloidosis. Therefore, if amyloidosis of the extraocular muscles is diagnosed, a systemic work-up is needed to rule out systemic amyloidosis, which is potentially life-threatening.

To describe a rare complication of phacoemulsification (Phaco) cataract extraction.

A phaco tip fracture occurred during the sculpting of the nucleus in a cataract extraction surgery of a 60-year-old woman. The surgeon introduced the second instrument through the side port to retrieve the broken portion of the tip while maintaining it inside the sleeve.

Phaco tip fracture is a rare but serious complication that all cataract surgeons should be able to manage safely. Main risk factors for phaco tip fractures are Aspiration Bypass System (ABS) phaco tip design and sterilization and reuse of instruments. A step by step plan of action was described in detail for a surgeon to manage a phaco tip fracture which mainly consists of removing the fractured phaco tip while it is still inside the sleeve to prevent any touch between the sharp broken edge of the tip and any intraocular component.

To describe the finding of bright hyperautofluorescent streaks in the peripheral retina in tuberous sclerosis.

A woman with a pathogenic TSC1 mutation and cutaneous manifestations of tuberous sclerosis underwent fundus examination and was found to have a cluster of thin, yellowish streaks in the inferior peripheral fundus of her left eye. The streaks were hyperautofluorescent in blue light and associated with irregular thickening of the photoreceptor-pigment epithelium complex on optical coherence tomography.

The cluster of outer retinal abnormalities in a sector of the peripheral retina in one eye of a TSC1 patient has features in common with the more centrally located and less numerous lesions called achromatic patches. The resemblance of the streak pattern with the pattern of hypoautofluorescence in X-linked retinopathies suggests that the streaks may represent a clone of cells derived from a single somatic mutation in TSC1. The identification of this lesion type expands the scope of conditions that can be diagnosed by fundus imaging.

To describe a case of massive spontaneous subconjunctival hemorrhage in a patient taking warfarin with a therapeutic international normalized ratio (INR).

Massive circumferential hemorrhagic chemosis, extensive periorbital and facial ecchymosis, and active arterial extravasation in the subconjunctiva which required cessation and reversal of anticoagulation. Findings gradually resolved over several months after discharge.

While subconjunctival hemorrhage, even in anticoagulated patients, is usually benign, rare examples of severe presentations exist. We present, to our knowledge, the first documented case of a subconjunctival hemorrhage necessitating cessation and reversal of anticoagulation in the setting of a therapeutic INR.

To present a case of a patient with human immunodeficiency virus (HIV) disease and Kikuchi-Fujimoto disease (KFD) who presented with a unique pattern of retinopathy.

A 7-year-old Taiwanese girl with HIV disease who was recently diagnosed with KFD had a sudden onset of blurry vision in both eyes one month after her KFD systemic symptoms had relatively resolved. Ophthalmic examination showed decreased visual acuity in both eyes (OU). On fundus examination, she had bilateral preretinal, subhyaloid, and vitreous hemorrhage that was more severe than anemic retinopathy.

Ocular manifestations in Kikuchi-Fujimoto disease are rare; however, if they occur, presentations may vary. The exact etiology of the disease has remained elusive and controversial. This case is the first report of a patient with HIV disease and KFD presenting with ocular involvement. Furthermore, bilateral preretinal, subhyaloid, and vitreous hemorrhage, which was beyond anemic retinopathy, is an unprecedented manifestation of KFD that has not been previously reported. This case highlights the necessity for clinicians to consider all possible differential diagnoses when evaluating patients with similar findings to identify the best therapeutic approach and avoid unnecessary treatment.

In this study, the health of fish Malapterurus electricus was examined, to serve as a reflection of the impact of anthropogenic disturbances in the Lekki lagoon. Eighty six samples of the fish were analysed for parasitic infections, heavy metals, microorganisms in their internal and external body parts while the proximate composition and fish condition factor were also determined using conventional methods. One parasite species, a cestode Electrotaenia malapteruri was found to infect the fish. Total parasite load was eighty five with a total prevalence of infection of 36%. Elements detected in sediment were of the order of Al>Fe>Mn>Pb>Cr>Zn>Cd>Ba>Cu>Ni while in water, it is Mn>Fe>Zn>Ba>Cd>Cr>Al>Cu>Ni>Pb. Metals analysed in the fish tissues were generally low and below regulatory limits. In the proximate analysis, moisture content has a value of 80.7%, while ash content had a value of 1.26%. Eight bacterial and two fungal species were isolated from the fish. The condition factor of fish varied between 1 and 2. The study provides valuable information for monitoring and management of heavy metal pollution in the aquatic ecosystem.Measuring corticosterone concentrations in feathers of poultry may be suitable to determine birds' exposure to stress. It is thinkable, that in laying hens such information could be helpful as an animal welfare indicator to evaluate adverse husbandry conditions and to predict the risk of developing behavioral disorders, such as feather pecking and cannibalism. Yet, there are some fundamental issues which remain unclear. Therefore, the objective of the current pilot study was to examine the inter- and intraindividual variation of pullets at the end of the rearing period, when most of the feathers are fully grown and animals are reaching sexual maturity. Flight feathers from both wings (n = 4), the tail (n = 2 - 3), and body feathers (n = 1 pool of 3 - 5 feathers) were taken from pullets (n = 10), genetics Lohmann Brown, at an age of 19 weeks who were reared in the same flock (N = 728). Corticosterone analysis was performed applying a validated protocol for laying hens. Results indicate not only high intraindividual, but also high interindividual variation.
