AI Article Synopsis
- The study aimed to evaluate the safety and effectiveness of subthreshold micropulse yellow laser treatment for a 77-year-old woman suffering from refractory pseudophakic cystoid macular edema following cataract surgery complications.
- After traditional treatments failed over 14 months, the laser intervention led to immediate resolution of the edema, which lasted for two months, although two relapses occurred before the final check-up.
- By the six-month follow-up, the patient's eye condition improved significantly with no edema, better visual acuity, and no reported complications, suggesting the laser treatment is a viable alternative to more invasive options.
Article Abstract
Purpose: To report the safety and efficacy of subthreshold micropulse yellow laser of 577 nm for a complex case of refractory pseudophakic cystoid macular edema.
Methods: A retrospective chart review of an interventional case report of three subthreshold micropulse yellow laser interventions for refractory pseudophakic cystoid macular edema.
Patient: A 77-year-old healthy female underwent pseudoexfoliative cataract surgery complicated by posterior capsule rupture and sulcus intraocular lens implantation. After 3 months, she required a scleral fixation of the same lens, due to a lack of capsular support and decentration of the intraocular lens. One month later, she experienced a severe pseudophakic cystoid macular edema (foveal thickness of 399 µm and best-corrected visual acuity of 20/80 Snellen). The condition was refractory to conventional treatments prior to subthreshold micropulse yellow laser interventions, including non-steroidal anti-inflammatory eye drops, topical steroids, oral indomethacin and three sub-Tenon's triamcinolone injections, attempted over a 14-month period.
Results: Subthreshold micropulse yellow laser treatment was performed and immediate resolution was achieved and maintained for 2 months. Two cases of edema relapse were observed at 3 months from initial laser treatment and again at 4 months from the second laser treatment. Final patient's follow-up at 6 months from the third laser treatment evidenced the absence of edema, improved visual acuity (foveal thickness of 265 µm/best-corrected visual acuity of 20/30 Snellen) and the absence of complications.
Conclusions: Subthreshold micropulse yellow laser seems to be a safe and effective treatment for short-term resolution of refractory pseudophakic cystoid macular edema after complicated cataract surgery and represents a useful alternative to expensive and invasive therapies. A trend towards a longer duration of edema resolution with every subthreshold micropulse yellow laser repetition was observed.

Current insights and challenges in the management of perifoveal vascular anomalous complex (PVAC): a systematic review of multimodal imaging features and treatment strategies.
Eye (Lond)
December 2024
IRCCS Ospedale Policlinico San Martino, Eye Unit, Genova, Italy.
The aim of this article is to comprehensively review the multimodal imaging (MMI) features that define perifoveal vascular anomalous complex (PVAC) and to update the optimal treatment strategies for this disorder with a focus also on the underlying pathogenetic mechanisms. This systematic review was performed based on a search of the PubMed and Embase databases of relevant papers on the subject of PVAC. PVAC is characterized by well-defined MMI findings, including remarkable morphological features with optical coherence tomography (OCT) and OCT angiography (OCTA).

Purpose: Assess the effectiveness of a subthreshold micropulse laser for treating a patient with polypoidal choroidal vasculopathy and subretinal fluid.
Observations: A 55-year-old female presented with left eye blurring vision and metamorphopsia, and her visual acuity was 20/60. Optical coherence tomography (OCT) and OCT angiography showed subretinal fluid and pigmented epithelium detachment with a small polyp under the retinal pigmented epithelium, which was diagnosed as polypoidal choroidal vasculopathy.

Purpose: To evaluate the treatment outcomes of subthreshold micropulse laser (SMPL) with a wavelength of 670 nm (red) for treatment-naïve diabetic macular edema (DME).
Methods: A retrospective observational study which included 42 eyes in 34 patients diagnosed with treatment-naïve DME was conducted. Twenty-one eyes underwent red SMPL and the other 21 eyes underwent intravitreal injection of aflibercept (IVA) as initial treatment and were followed up for 12 months.

Purpose: To assess the safe, lowest effective laser power of subthreshold micropulse laser (SML) for treating acute and chronic central serous chorioretinopathy (CSC) in Chinese patients.
Methods: Patients were distinguished with acute or chronic CSC based on focal or diffuse retinal pigment epithelium (RPE) leakage on fundus fluorescein angiography (FFA), with or without widespread RPE decompensation. Patients were categorized into five groups and treated with 577 nm yellow SML according to 50% titration power.
