Purpose: Osteomyelitis of the orbital bones presenting as an orbital cellulitis is a rare form of extrapulmonary tuberculosis (TB). We report a rare case of tubercular osteomyelitis of the orbital bones presenting as a periorbital cellulitis. Case Report: A seven-year-old female child presented to our tertiary eye care center with swelling involving the right eyelids and the right cheek for two months. She had been provisionally diagnosed elsewhere as pre-septal cellulitis and had been given oral antibiotics. We clinically diagnosed her as orbital cellulitis, but her non-responsiveness to intravenous antibiotics prompted us to get a contrast enhanced computed tomography (CECT) of the orbit and paranasal sinuses, which was suggestive of tubercular etiology. However, the patient had no foci for TB elsewhere. We used a relatively new, but rapid test, called Cartridge-based Nucleic Acid Amplification Test (CBNAAT) on the pus aspirate which was positive for TB. Thereafter, the patient was started on anti-tubercular treatment to which she responded wonderfully. Conclusion: A high index of suspicion should be kept for TB infection in cases of orbital cellulitis with unusual clinical behavior in an endemic region such as India.

We report the case of a 22-year-old male, presenting with right enophthalmos and intermittent exophthalmos observed after valsalva maneuver. Orbital imaging revealed a retrobulbar vascular lesion with multiple phleboliths suggestive of orbital varices. On magnetic resonance angiography, no obvious feeder vessel could be delineated. We decided to manage the patient conservatively, in the absence of complications such as proptosis with corneal exposure, optic nerve compression, orbital hemorrhage. Orbital varix is a low flow vascular anomaly which generally presents with an intermittent exophthalmos. Development of enophthalmos associated with orbital varices as in our case, is very rare.

BACKGROUND: Pterygium is very common in India and is usually removed by limbal conjunctival autograft transplantation (LCAT), which, despite being the first-line therapy, is still associated with recurrences of up to 18%. OBJECTIVES: To compare the safety and efficacy of topical cyclosporine A (CsA) and interferon (IFN) alpha-2b in the prevention of postoperative recurrence of pterygium. METHODS: A total of 40 patients with primary pterygium were randomized into two equal groups, Group C and Group I. Both the groups underwent LCAT, with Group C kept on topical cyclosporine 0.05% (CsA) 4 times daily and Group I on topical IFN alpha 2b 0.2 million IU 4 times daily postoperatively for 3 months. Pre- and posttreatment best-corrected visual acuity (BCVA), recurrence, and complications were assessed at day 1, week 1, 1 month, and 3 months. RESULTS: The mean preoperative BCVA of 0.51 ± 0.18 and 0.51 ± 0.23 improved to 0.13 ± 0.13 and 0.13 ± 0.13 in Group C and Group I, respectively, after 3 months of treatment ( P < 0.0001). Recurrence was seen in 2 cases in Group C and in 1 case in Group I at 3 months. No significant complications occurred in either of the groups. CONCLUSION: Topical CsA and IFN Alpha-2b are newer efficacious adjuvants with LCAT for prevention of postoperative pterygium recurrence.
