Purpose: This study aimed at evaluating the intermediate-term efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-TSCPC) in cases of uncontrolled glaucoma. Methods: Patients with moderate to advanced glaucoma and uncontrolled intraocular pressure (IOP) despite maximally tolerable antiglaucoma medications were selected to undergo MP-TSCPC using the MP3 handpiece with the Iridex Cyclo G6 (IRIDEX Laser Systems). Follow-up examinations took place on a regular basis until 15 months postoperatively. Results: Seventy-five eyes of 69 patients (53.6% male patients) were included. Mean age was 55.5±22.9 years. Primary open-angle glaucoma was the most common diagnosis. Corrected distance visual acuity at baseline ranged between 0 and 2.1 logMAR. Mean prelaser IOP was 26.0±7.91 mm Hg. This was reduced significantly to 13.8±5.6 mm Hg (44.0% reduction, P<0.001) at week 1, and to 18.0±7.7, 18.4±7.1, 16.7±6.2, 15.1±4.1, 15.7±5.32, and 14.8±5.50 mm Hg at months 1, 3, 6, 9, 12, and 15, respectively. The mean number of antiglaucoma drops decreased significantly up to 12 months of follow-up (P=0.008) and that of oral acetazolamide tablets decreased significantly up to 15 months (P<0.001). The success rate decreased progressively with time, reaching 81.4% at 6 months and 73.3% at 1 year. No major postoperative complications were encountered, and no eye lost vision completely. Conclusions: MP-TSCPC is an efficient noninvasive glaucoma treatment that achieves sustained IOP reduction and reduced need for ocular antihypertensive medications for up to 15 months. The optimal laser parameters to achieve the best success rate with the least side effects still need to be determined.

Choroidal tuberculoma is a rare ocular form of tuberculosis (TB) that raises both a diagnostic and a therapeutical challenge, especially when occurring without other manifestations of the disease. This study reports the case of a 27-year-old woman who had a unilateral drop of vision (20/100) with ocular pain. Her fundus examination revealed an elevated juxtapapillary choroidal mass measuring 892 µm in diameter, as calculated by optical coherence tomography (OCT), and associated with a serous retinal detachment involving the macula. The diagnosis of choroidal tuberculoma was established by positive QuantiFERON-TB and tuberculin skin test. Laboratory and imaging workup ruled out pulmonary and systemic TB as well as other possible etiologies. Antituberculosis therapy was started and led to an improved visual acuity (20/30) and a shrinkage of the tuberculoma to a diameter of 499 µm at 3 months. This is one of the few reported cases of solitary choroidal tuberculoma in a patient with no other sign of TB. It sheds light on the place of OCT in the diagnosis and follow-up of the choroidal mass, in terms of measuring the size of the mass and revealing the associated serous retinal detachment and the distinctive “contact sign” between the neurosensory retina and the retinal pigment epithelium (RPE)–choriocapillaris layer surmounting the tuberculoma.
