Published: June 2024

Purpose: To report a case of unsuccessful transscleral cyclophotocoagulation in a patient with OCA1A tyrosinase-negative oculocutaneous albinism.

Observations: A 35-year-old Asian female with molecularly diagnosed OCA1A (tyrosinase-negative) oculocutaneous albinism and unilateral severe mixed mechanism glaucoma underwent transscleral cyclophotocoagulation on two separate occasions to treat elevated intraocular pressure. The intraocular pressure remained markedly elevated approximately 1 month following two separate treatments of transscleral cyclophotocoagulation while using high energy settings. The poor efficacy of both cyclophotocoagulation treatments was most likely due to a lack of melanin in the setting of oculocutaneous albinism.

Conclusions And Importance: Cyclophotocoagulation in patients with oculocutaneous albinism is less likely to yield a desired lowering of intraocular pressure due to the absence of melanin.

Purpose: To evaluate the outcomes of slow-coagulation transscleral cyclophotocoagulation (SC-TSCPC) in pseudoexfoliation glaucoma (PXG).

Methods: A single-center, retrospective non-comparative study including consecutive patients with medically uncontrolled PXG who underwent SC-TSCPC (1250-milliwatt power and 4-second duration). The primary outcome measure was surgical success (defined as intraocular pressure (IOP) between 6 - 21 mmHg with ≥20% reduction compared to baseline and no need for further glaucoma surgeries or development of vision-threatening complications).

Purpose: To evaluate the efficacy and safety of Ahmed glaucoma valve (AGV) implantation with subsequent trans-scleral diode cyclophotocoagulation (CPC) as the main intervention if IOP remained medically uncontrolled.

Patients And Methods: Charts of 108 consecutive eyes (90 patients) that underwent AGV implantation from 2003 to 2018 at a single clinical practice were retrospectively reviewed. The procedure was considered a failure if any of the following occurred: additional incisional glaucoma surgery, IOP >21 mmHg or < 20% reduction from baseline on 2 consecutive study visits after 3 months, IOP ≤ 5 mmHg on 2 consecutive study visits after 3 months, loss of light perception, or AGV removal.

Introduction: To investigate 5-year outcomes on intraocular pressure (IOP) and safety of micropulse transscleral cyclophotocoagulation (TSCPC) in patients with glaucoma.

Methods: Patients with mild to advanced glaucoma who underwent a standardized micropulse TSCPC procedure at the University Eye Clinic Maastricht from November 2016 to February 2019 were included.

Results: A total of 165 eyes were included, with outcomes for 112 eyes available after 5-year follow-up.

Aim: To evaluate the efficacy and safety of MicroPulse transscleral laser therapy (MPTLT) for cyclophotocoagulation in the treatment of glaucoma with different doses of energy.

Materials And Methods: A retrospective review was done of 136 eyes in 90 patients treated with MPTLT between 2018 and 2022. Intraocular pressures (IOP) at follow-ups were compared with a paired student -test and treatment outcomes with a Chi-squared test.

Purpose: To describe an alternative technique used in massive post-traumatic cyclodialysis. Classic techniques such as direct cyclopexy are performed ab externo and entail a higher risk of endophthalmitis or ciliary body hemorrhage. Therefore we present a case report using combined sewing machine technique cyclopexy with transscleral diode cyclophotocoagulation for complete post-traumatic cyclodialysis.
