Retinitis pigmentosa is not usually treated with laser therapy, and laser therapy is feasible when patients present with retinal tears and shallow detachments, such as traditional laser photocoagulation through thermal effects and subthreshold micropulse photocoagulation targeting the retinal pigment epithelium in the macula. Retinitis pigmentosa is a common hereditary retinal disease in ophthalmology, for which there is no effective clinical treatment. Current research has found that stem cell transplantation can be effective, but there are fewer clinical trials, it has not been promoted in clinical practice, and long-term efficacy has yet to be verified. Laser therapy is more commonly used to treat retinal tears and shallow detachments. Traditional laser photocoagulation is to reduce the burden on the remaining retinal pigment epithelium by forming a scar in the retinal pigment epithelium through the thermal effect so that the photoreceptor cells die and are lost. In contrast, subthreshold micropulse photocoagulation can be implemented repeatedly, mainly stimulating the retinal pigment epithelium in the macular area to produce heat shock proteins to inhibit photoreceptor cell apoptosis, and does not cause damage to retinal cells. It is recommended that patients with retinitis pigmentosa seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
