Posterior segment involvement in systemic lupus erythematosus – A series from South India

Purpose: To report the spectrum of posterior segment manifestations and visual outcomes in a large series of patients with systemic lupus erythematosus (SLE). Methods: Retrospective study at a tertiary referral eye center in south India between 2016 and 2022. Results: Charts of 109 patients diagnosed to have SLE were retrieved from our medical database. Only nine cases of SLE (8.25%) had posterior segment involvement. The male: female ratio was 1:8. The mean age was 28 years. Unilaterality was the most common presentation in eight cases (88.89%). Lupus nephritis was the most common systemic presentation in five cases (55.56%). Antiphospholipid antibodies (APLA) positivity was seen in two cases (22.22%). Ocular manifestations included microangiopathy (cotton wool spots) in one case, occlusive retinal vasculitis with cotton wool spots in four cases (five eyes), optic disc edema with combined venous and arterial occlusion (one case), central retinal vein occlusion with cotton wool spots and hemorrhages (one case), macular edema (four cases), posterior scleritis with optic disc edema and exudative retinal detachment in the posterior pole (one case), and tubercular choroidal granuloma (one case). Treatment included systemic steroids, hydroxychloroquine sulfate (HCQS), and immunosuppression in all cases, blood thinners in two cases, and laser photocoagulation in four cases. HCQS?related retinal toxicity was not seen in any of the 109 cases. Ocular manifestation was the initial presentation of SLE in one case. Visual outcome was poor in three cases. Conclusion: Presence of posterior segment findings in cases with SLE may suggest a severe systemic disease. Early detection and aggressive treatment result in better visual outcomes. Ophthalmologists could play a vital role in guiding systemic therapy.

Medical Management of Uveitis – Current Trends.

Uveitis is a challenging disease to treat. Corticosteroids have been used in the treatment of uveitis for many years. Immunosuppressives are gaining momentum in recent years in the treatment of uveitis. In this article we present an overview of current treatment of uveitis and the major breakthroughs and advances in drugs and ocular drug delivery systems in the treatment of uveitis.

Large drusen following long-standing retinal detachment.

We report an interesting finding of multiple large drusen in an eviscerated eye with a longstanding retinal detachment. The origin and composition of the drusen is also speculated on the basis of special stains.

Melkersson-Rosenthal syndrome in a patient with tubercular panuveitis.

We report a rare presentation of Melkersson-Rosenthal syndrome in a patient with tubercular panuveitis. A 45-year-old male being treated with antitubercular therapy for tubercular panuveitis presented with unilateral, non-pitting right upper eyelid edema. Excision biopsy showed granulomatous inflammation involving the lymphatics. Immunohistochemistry confirmed the presence of histiocytes around the lymphatics.

Coin-shaped epithelial lesions following an acute attack of erythema multiforme minor with confocal microscopy findings.

We report an interesting ocular finding of bilateral multiple coin-shaped epithelial lesions along with the confocal microscopy findings in a patient following an acute attack of erythema multiforme (EM) minor. A 30-year-old male presented with a history of watering and irritation in both eyes of three days duration. He was diagnosed to have EM minor and was on oral acyclovir. Slit-lamp examination revealed multiple coin-shaped epithelial lesions. Confocal microscopy showed a corresponding conglomerate of hyper-reflective epithelial lesions. The corneal lesions resolved over six weeks with oral steroids and acyclovir. An immunological mechanism is suspected.

Insect wing tarsal foreign body causing conjunctival granuloma and marginal keratitis.

A 37 year old male was referred to our centre for management of episcleritis with peripheral keratitis in the right eye. He had a history of ocular discomfort in the right eye of 1 week duration. Slitlamp examination revealed marginal keratitis between 12'o clock to 2'o clock positions in the right eye. Lid eversion revealed an insect wing on the tarsal conjunctiva along with an adjacent conjunctival granuloma. The area of the marginal keratitis corresponded to the area of the foreign body and the conjunctival granuloma. The probable mechanism of the development of marginal keratitis and the conjunctiva granuloma is speculated in this case report.

Amyloidosis of lacrimal gland.

Primary localized amyloidosis of lacrimal gland is a rare occurrence. This report describes a female patient with isolated amyloidosis of the lacrimal gland. A 45-year-old Indian woman presented with a swelling over the left lacrimal gland region. Computed tomography showed uniform enlargement of the lacrimal gland. A lacrimal gland biopsy revealed amyloidosis. No systemic involvement was detected on further investigation. To our knowledge, this is the first report of lacrimal gland amyloidosis from India and our report also highlights the importance of lacrimal gland biopsy in diagnosing lacrimal gland masses.

Utility of QuantiFERON TB gold test in a south Indian patient population of ocular inflammation.

Aim: To study the utility of interferon-γ release assays (QuantiFERON TB gold test) in a south Indian patient population of intraocular inflammation. Design: Evaluation of a diagnostic test- a pilot study from January 2007 to October 2008. Materials and Methods: QuantiFERON TB gold test was performed on the following groups of patients following an informed consent. Group A included healthy volunteers without any exposure to tuberculosis (TB) or past history of TB (n=22). Group B included patients with active systemic TB diagnosed by the demonstration of acid-fast bacilli or by the histopathology finding of caseation with granuloma formation from the sputum, lymph node, skin or intestinal biopsies (n=26). Group C included patients with uveitis of known etiologies other than intraocular TB without any history of exposure to active TB (n=21). Group D included patients with a diagnosis of presumed intraocular TB, who responded to antitubercular therapy by decreased or no recurrences following treatment and with a minimum of nine months follow-up following initiation of antitubercular therapy (n=39). Results: The sensitivity and specificity of the QuantiFERON TB gold test to pick up active systemic TB was 58% and 77% respectively. The sensitivity and specificity of the QuantiFERON TB gold test to pickup intraocular TB was 82% and 76% respectively. Conclusions: QuantiFERON TB gold test alone may not be specific for intraocular TB. The significance of this test in a case scenario needs to be interpreted with clinical presentation and other evidences for intraocular TB.

Vision recovery in human immunodeficiency virus-infected patients with optic neuropathy treated with highly active antiretroviral therapy: A case series.

We describe three patients with bilateral, presumed human immunodeficiency virus (HIV)-induced optic neuropathy. The above diagnosis was made by exclusion of infectious agents and neoplasms by detailed clinical and laboratory investigations. All patients had decreased visual acuity, pale optic discs and constriction of visual fields. Improvement was documented in all three patients for visual acuity and in one patient for visual fields following treatment with highly active antiretroviral therapy (HAART). Optic neuropathy in HIV-positive patients does not necessarily carry a poor prognosis even when a treatable cause is not found. This article emphasizes the effectiveness of HAART in presumed HIV-induced optic neuropathy.

Bilateral retinitis following chikun- gunya fever.

A 35-year-old male with a history of chikungunya fever, presented with diminution of vision in the right eye of one-week duration. His best corrected visual acuity (BCVA) was counting fingers 2 meters and 20/20 (Snellens) in the right and left eyes respectively. A diagnosis of neuroretinitis was made in the right eye while left eye showed features of retinitis. ELISA (serum) and polymerase chain reaction (aqueous) were positive for herpes simplex virus. The lesions did not show any response to antiviral or steroid treatment and appeared to be self-limiting. At five months follow-up, lesions had resolved well with BCVA of 20/120 and 20/20 in the right and left eyes respectively.

Posterior polymorphous dystrophy is a rare corneal dystrophy, usually detected by chance. This case series describes the morphologic features in the three different types of posterior polymorphous dystrophy using confocal microscopy.

Triple A syndrome with ophthalmic manifestations in two siblings.

Triple A syndrome (Allgrove syndrome) is a rare, autosomal recessive disorder characterized by adrenocorticotropic hormone resistant adrenal insufficiency, alacrima, achalasia of the esophageal cardia, progressive neurological degeneration and occasionally autonomic instability. We report the ophthalmic manifestations in 2 siblings from a consanguineous family with this syndrome. A routine ophthalmic examination showed absence of palpebral portion of lacrimal gland, dry eyes and sluggish pupillary reflexes in both eyes of these patients. Both of these patients had achalasia cardia while the boy additionally had increased serum cortisol levels. Topical ocular lubricants were prescribed for both of them and Heller's cardiomyotomy with fundus plication was done for achalasia. These cases would create an awareness of this rare condition in ophthalmology in addition to suggesting its management.

NK/T-cell lymphoma in AIDS.

A 42-year-old man diagnosed to be HIV positive and on highly active antiretroviral treatment (HAART), presented with double vision and gradual drooping of the left eyelid. He had left 3rd cranial nerve palsy and partial right lower-motor-neuron facial palsy. CT of the PNS revealed soft tissue filling the right maxillary sinus antruin. Further workup showed the mass to be an NK/T cell lymphoma.

Determination of carbonyl group content in plasma proteins as a useful marker to assess impairment in antioxidant defense in patients with Eales' disease.

PURPOSE: Formation of protein carbonyl groups is considered an early biomarker for the oxidant/antioxidant barrier impairment in various inflammatory diseases. We evaluated the intensity of free radical reactions in patients with Eales' disease, an idiopathic inflammatory condition of the retina. METHODS: Twenty patients with Eales' disease in active vasculitis stage, 15 patients with Eales' disease in healed vasculitis stage and 20 healthy control subjects were recruited for the study. Plasma protein carbonyl groups,plasma glutathione (GSH) superoxide dismutase (SOD) activity and thiobarbituric acid reactive substances (TBARS) were determined in erythrocytes. RESULTS: Plasma protein carbonyl content was elevated by a factor of 3.5 and 1.8 respectively in active and healed vasculitis stages. The increase of carbonyl group content in active and healed stage of patients with Eales' disease correlated with diminished SOD activity and GSH content. There was also increased accumulation of TBARS in active and healed vasculitis stages of Eales' disease, and this correlated with diminished SOD activity. CONCLUSION: Our results showed that protein carbonyl group content increases with severity of Eales' disease. The increase in carbonyl content correlated with diminished antioxidant status. This confirms an earlier report that free radical mediated tissue damage occurs in Eales' disease. The determination of protein carbonyl content may be used as a simple biomarker to monitor the efficacy of antioxidant supplementation in controlling retinal vasculitis in patients with Eales' disease.

Uveal metastasis from a bronchial carcinoid tumour.

A rare case of bronchial carcinoid tumour metastasis to the ciliary body and the choroid with clinical, diagnostic and histopathological correlation is reported.

Ocular manifestations of Wegener's granulomatosis. Analysis of nine cases.

PURPOSE: To report a series of nine patients of Wegener's granulomatosis (WG) with diverse ocular and systemic manifestations. METHODS: Retrospective analysis of nine consecutive patients seen between 1987 and 2002. RESULTS: The mean age at the time of diagnosis was 43.89 years (range: 33-56 years). Redness, pain and photophobia (8 patients) were the common presenting complaints. Sinusitis (6 patients) and arthralgia (6 patients) were the commonly associated systemic complaints. Necrotising scleritis with peripheral keratopathy (6 patients) was the most common ocular sign. Serum antibodies against the cytoplasmic component of neutrophils and monocytes (cANCA) were positive in 7 of 8 patients. Biopsy diagnosis was done in one patient for whom cANCA was not done. Cyclophosphamide and corticosteroids alleviated the symptoms in 6 patients. Ocular and systemic condition remained stable in 7 patients. One patient expired due to the severity of the disease and another patient was lost to follow-up. CONCLUSIONS: Scleritis with peripheral corneal involvement was the most commonly observed ocular manifestation of WG in our series. cANCA was a useful adjunct in the diagnosis of WG. When clinical and serologic findings were inconclusive, biopsy remained indispensable. A combination of cyclophosphamide and corticosteroids is essential and critical not only for the ocular condition but also for the survival of the patient.
