The investigators plan to recruit 20 children and adolescents (ages 0 to 17 years, inclusive) from the Children's Hospital Los Angeles (CHLA) ophthalmology clinics who have lagophthalmos affecting one or both eyes and have been recommended to use medical tape or other eyelid closure device to help keep their eyelids closed. The aims are to 1) objectively measure the improvement in lagophthalmos from baseline while using the Tarsus Patch, and 2) evaluate patients' and parents' experience with survey questions related to complications, comfort, ease of use, and preference for using the about the Tarsus Patch.
PROCEDURES INVOLVED
* Study visit (Day 1 of study, 60 minute commitment):
* At the study visit, informed consent will be obtained by the study coordinator or investigator.
* Once consent is obtained, the enrolled subject then undergoes an ophthalmic history and examination, including dilated examination if deemed necessary for their usual ophthalmic care. The history will include usual questions asked at a follow-up visit about ocular health and will also include details about how often, in which eye, and with what method they close their eyelids at night.
* The examination will include standard measures of vision, ocular surface health, and eyelid position and function.
* If the subject has unilateral lagophthalmos, then the involved eye will be designated as the study eye. If the subject has bilateral lagophthalmos, then the eye with more severe lagophthalmos will be designated as the study eye.
* The parent will receive an explanation about the procedures of the study.
* The study investigator will choose which Tarsus Patch size (pediatric or adult) will fit best on the child's eyelid. With the proper size, the parent will then be shown how to properly place the Tarsus Patch on the study eye, and questions will be answered about how to properly place the patch on the eye.
* The parent will then be given the following items to take home: 6 patches (this includes a few extra patches in case they are needed), and a copy of the study consent form including email and phone number to reach the study team should they have any questions
* To minimize risk, the parent will be informed that if the subject has any discomfort with an of the study protocols, they should stop the use of the Patch call the study team to discuss how to address the issue.
* At home portion (Day 1-3 of study):
\- Each night for 3 nights, the parent should place a new Tarsus Patch on the subject's study eye and then place a ½ cm strip of ophthalmic ointment or gel into the study eye. The parent should then help remove the patch the next morning and throw it away.
* Phone survey (Day 4):
* A study investigator will call the parents to have them respond to the Parent Survey over the phone in the absence of the study subject.
* If the subject is 10 years of age or older and cognitively able to answer the survey questions, then they will be asked to answer the Subject Survey over the phone with the help of the parent.
