Purpose: We report a case of macular, serous retinal detachment associated with hypotony in a patient with pachychoroid disease developing after Ahmed valve implantation.
Case summary: A 77-year-old male visited our clinic with uncontrolled intraocular pressure (IOP; 32 mmHg) in his left eye despite maximal tolerable medical therapy. A prolapsed vitreous filled the anterior chamber. Swept-source optical coherence tomography (SS-OCT) revealed that the subfoveal choroidal thickness was about 510 μm, indicating pachychoroid. Vitrectomy was performed to remove the prolapsed vitreous. The IOP remained 32 mmHg 3 weeks after vitrectomy. Ahmed valve implantation was performed and hypotony developed 10 days postoperatively. Choroidal detachment was apparent and SS-OCT revealed macular accumulation of subretinal fluid. The subfoveal choroidal thickness increased to a level beyond the SS-OCT measurement range. Partial tube ligation was performed to treat the hypotony 18 days after Ahmed valve implantation; the IOP decreased to 14 mmHg at 6 weeks postoperatively. The macular, serous retinal detachment disappeared and the subfoveal choroidal thickness fell to the preoperative value.
Conclusions: Hypotony after Ahmed valve implantation can manifest as serous retinal detachment under the fovea accompanied by an increase in choroidal thickness in an eye with underlying pachychoroid.
