Ophthalmic manifestations in hematological malignancies: An observational study from a tertiary care health center in Eastern India.

PURPOSE: This study aimed to document the spectrum of ocular manifestations of hematological malignancies presenting to a tertiary health center in Eastern India and their association with blood parameters. METHODS: This hospital-based cross-sectional study was conducted from August 2021 to July 2022. Patients diagnosed with leukemia, lymphoma, and multiple myeloma were enrolled in the study. A comprehensive ophthalmic evaluation was done in each case. RESULTS: A total of 97 patients with a confirmed diagnosis of hematological malignancies and meeting the inclusion and exclusion criteria were included in the study. Ocular manifestations were noted in 48 (49.48%) patients. Acute lymphocytic leukemia accounted for 35.4% of cases, followed by acute myeloid leukemia (31.25%), lymphoma (4.2%), and minimum manifestation in multiple myeloma (2.1%) patients. Among 48 patients with ocular manifestations, anterior segment involvement was found in 6.2% of cases, with subconjunctival hemorrhage being the most common, and the posterior segment was involved in 100% of patients, with intraretinal hemorrhages being the most common manifestation. A statistically significant association was noted between hemoglobin, total red blood cell count, and total platelet count with posterior segment manifestations ( p < 0.001). On multivariable logistic regression, only total leucocyte count and total platelet count were significant predictors for ocular manifestation. CONCLUSION: Indirect involvement of the retina is the most common ocular pathology in hematological malignancies, with intraretinal hemorrhages being the most common finding. Ophthalmic examination is highly recommended as a part of the routine evaluation at the time of diagnosis of hematological malignancies and periodically thereafter to diagnose any ocular involvement.

An optical coherence study on optic disc parameters and peripapillary retinal nerve fiber layer thickness in patients with optic disc edema.

PURPOSE: This study aimed at evaluation of patients diagnosed with optic disc edema (ODE) in terms of demographics, etiology, clinical presentation, and optical coherence tomography parameters. METHODS: An observational cross-sectional study was conducted from August 2021 to July 2022. Patients diagnosed with ODE underwent comprehensive ophthalmic evaluation. Peripapillary retinal nerve fiber layer (RNFL) thickness and optic nerve head parameters were assessed using optical coherence tomography. Radiologic investigations were done as deemed necessary. RESULTS: One hundred and forty-eight eyes with ODE (134 eyes from 67 patients with bilateral ODE and 14 eyes from 14 patients with unilateral ODE) and 148 eyes of age- and gender-matched control group were included in the study. The mean age of the study population was 31.51 ± 13.33 years, with 44 (54.3%) males and 37 (45.6%) females. Bilateral ODE was seen in 82.7% of patients. Idiopathic intracranial hypertension was the most common cause of bilateral ODE, and nonarteritic anterior ischemic optic neuropathy was the most common cause of unilateral presentation. Decreased vision and headache were the main symptoms reported by a majority of patients. Peripapillary RNFL thickness was significantly increased in the ODE group compared to controls. CONCLUSION: The current study provides the clinical profile and optic disc and RNFL measurements of ODE patients in an Eastern Indian population. Detailed history and careful evaluation are necessary, as the treatment strategy is highly dependent on the underlying etiologies.

Unilateral branch retinal vein occlusion with vitreous hemorrhage mimicking Terson's syndrome.

We report a case of unilateral traumatic vitreous hemorrhage following injury to the anterior cranium. A 55-year-old female presented with gradual loss of vision in her left eye following trauma to the anterior cranium. Funduscopy revealed fresh vitreous hemorrhage. Conservative management was futile with further visual deterioration over the next 2 weeks. During pars plana vitrectomy, fresh retinal hemorrhages were noted along the superotemporal (ST) vein suggesting bleed due to vein rupture. Postoperative fundus fluorescein angiography indicated ST branch retinal vein occlusion. Since trauma can be an inciting factor for both, this case could be a variant of Terson's syndrome.

Ocular manifestations in HIV patients attending a tertiary care hospital in Eastern India and correlation of posterior segment lesions with CD4+ counts.

PURPOSE: We aimed to study the ocular manifestations in human immunodeficiency virus (HIV)-infected patients and the correlation of posterior segment lesions with CD4+ counts. METHODS: This hospital-based, cross-sectional study enrolled HIV-positive patients attending the ophthalmology department of a tertiary care hospital in Eastern India. Complete demographic information was obtained for each patient. Comprehensive ophthalmic evaluation was done in each case. RESULTS: A total of 184 HIV-positive patients were enrolled in the study. Ocular manifestations were detected in 62 cases. The prevalence of ocular manifestations in the present study was 33.69%. Mean age of patients included in the study was 34.8 ± 10.77 years. Prevalence of ocular manifestations was highest in the age group of 30-39 years (41.93%). Highest prevalence of ocular manifestations was noted in patients with low level of education and poor socioeconomic status. Sexual transmission was the major route of HIV transmission (in 92% of cases). Posterior segment lesions were seen in 69.35% of cases. HIV retinopathy was the most common posterior segment manifestation noted in 25 eyes. Significant positive correlation was noted between severities of posterior segment findings and CD4+ counts, which we found to increase with decrease in CD4+ counts (P < 0.001). CONCLUSION: Detailed ophthalmic evaluation including fundus examination is must in all cases of HIV/acquired immunodeficiency syndrome (AIDS) patients as it may help in early diagnosis, treatment, and prevention of sight-threatening complications due to opportunistic infections.

Pseudo endophthalmitis following intravitreal triamcinolone acetonide for cystoid macular edema in a post-vitrectomised eye.

Post-operative endophthalmitis is a vision threatening complication following intraocular surgery requiring prompt treatment. Clinical picture mimicking infectious endophthalmitis can rarely be produced following intravitreal triamcinolone acetonide injection. A 65-year-old male with previous history of pars plana vitrectomy and lens removal was diagnosed with post-operative cystoid macular edema in his right eye. He received intravitreal triamcinolone acetonide injection in his right eye. Two days following the injection he complained of further reduction in vision and presented with a clinical picture resembling infectious endophthalmitis. Nil active intervention was done. There was significant improvement in vision one week following the injection. Ophthalmologists should be aware of this clinical scenario so that excessive and unwarranted treatment can be avoided.

Bilateral disc edema: An unusual presentation of renal tuberculosis in a child.

Renal tuberculosis (TB) is a rare clinical disorder in the pediatric population. A 15-year-old female presented with intermittent blurring of vision in both eyes associated with fever, abdominal pain, and weight loss. Fundus examination showed bilateral disc edema. Her blood pressure was 220/110 mmHg. Renal parameters were deranged with bilaterally enlarged kidneys. Renal biopsy was suggestive of epithelioid cell granuloma with Langhans type giant cells. The patient was diagnosed with as a case of refractory hypertension due to tubercular interstitial nephritis with bilateral Grade IV hypertensive retinopathy. She was started on antitubercular therapy and antihypertensives. There was a complete resolution of disc edema 2 months following initiation of therapy. Optic disc edema can be a presenting sign in renal TB. Early diagnosis and prompt referral can be associated with good visual and systemic outcomes.
